Positioning apparatus of a memory-card connector
Abstract
The invention relates to a positioning apparatus of a
memory-card connector, which mainly provides an arm-slice extended
sideward from its cap to press over outer or fixed end of a control
rod. A space is provided at a position relating to inner or active
end of the control rod. The arm-slice can provides enough elastic
strength for pressing the control rod at certain area as moved in a
slider of the connector. And the space allows the active end of the
rod being moved without limitation that the connector can therefore
be manufactured more thinly for convenient utilization.

2. A positioning apparatus of a memory-card connector comprising: a
slider; a control rod operably coupled to the slider, the control
rod having outer and active end portions and an elongate
intermediate portion extending longitudinally therebetween; a cap
disposed at least partially over the control rod and slider; and,
an arm-slice having a first portion projecting from the cap to be
longitudinally spaced from the active end portion of the control
rod and to extend transversely over the intermediate portion of the
control rod, the arm-slice terminating at a second portion engaging
the outer portion of the control rod.
Description
FIELD OF THE INVENTION
[0001] The present invention relates to an improvement of a
positioning apparatus of a memory-card connector, which includes an
elastic arm-slice for effectively positioning a control-rod
relating to a slider placed in the connector and the connector can
be thinner for convenient use.
BACKGROUND OF THE INVENTION
[0002] It is known that a memory-card with small volume is widely
used for storing a large amount of electronic data. The memory-card
must be received in a connector for reading the data. The method of
connection between the memory-card and the connector is to insert
the memory-card into the connector directly. In order to take out
the memory-card from the connector, one can just press the
memory-card again. The movement and structure are shown in FIG. 1
to 4. A slider (2) is placed in one side of the connector (1),
which has an inner spring (21) and a front Y-type groove (22) with
a positioning block (23) therein. In the groove (22), there are
four different levels provided around the block (23). Hence, an
active end (31) of a control-rod (3) can be moved around the block
(23). As shown in FIGS. 1 and 2, the connector (1) is empty before
a memory-card is inserted. When the memory-card is inserted into
the connector (1), it will press the slider (2) to move inward. At
this time, the active end (31) of the control-rod (3) is moved
alone the inner levels around the block (23), as the imaged line
shown in FIG. 2, to a stable position at FIG. 3 for secure
engagement, in which the memory-card is received in the connector
(1). When to press the memory-card again, the slider (2) will be
moved inward and the active end (31) of the control-rod (3) will be
released from the block (23) and then moved alone the outer levels
around the block (23) to the original position when the slider (2)
is pushed outward by the spring (21), as imaged line shown in FIG.
4. The memory-card can be then taken out from the connector
(1).
[0003] In above conventional movement, it contains the structure
including the control-rod (3) moved around the block (23) for
engaging and releasing the memory-card. It is found that a
necessary means must be provided in such prior apparatus. That is
an elastic slice (41) must be formed on a cap (4) of the connector
(1) for pressing the control-rod (3) received in the groove (22) of
the slider (2) all the time. As shown in FIGS. 5 and 6, the known
elastic slice (41) has a long length that is not effective to
elastically press the control rod (3). Moreover, in order to
prevent from pushing the long elastic slice (41) overhead during
movement of the control-rod (3), the thickness of the prior
connector (1) cannot be reduced effectively.
SUMMARY OF THE INVENTION
[0004] The present invention is to provide an improved positioning
apparatus of a memory-card connector, which includes an arm-slice
extended from the cap sideward and just contacted with the outer
end of the control rod. It provides enough elastic force to press
the control rod. Now, accompanying with the following drawings, the
character of the present invention will be described here and
after.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] Please refer to FIGS. 7 and 8, the present invention relates
to an improvement of a positioning apparatus of a memory-card
connector, which includes a conventional slider (2) and a control
rod (3). The character of the present invention is to provide an
arm-slice (42) extended form the cap (4) sideward to press only the
outer portion of the control rod (3). A space (43) is formed at the
position relating to the active end (31) of the rod (3).
[0016] Please also refer to FIGS. 9 and 10, it can be found that
the active end (31) of the control rod (3) will be prevented from
limiting because of the space (43) while it is moved in the groove
(22) of the slider (2). Hence, a thinner connector (1) can be
manufactured by the present invention (Please compare with the
FIGS. 5 and 7). Moreover, since the arm-slice (42) is extended
sideward at middle position relating to the control rod (3), it can
provide enough elastic strength for pressing the control rod (3)
moved at corrective area. The application of the arm-slice is
obviously better than any prior art and is utilized.
[0017] Accordingly, the present invention should be allowed for
patent based on its improvement.
